1894KeithA

A fragment from the article by Keith A. The ligaments of the catarrhine monkeys, with references to corresponding structures in man (1894). The paper discusses the development, anatomy, and presence of the ligamentum capitis femoris (LCF) in various monkeys. The author found in an experiment that the gibbon's LCF strength is more than 11 kg. For reference: the black-handed gibbon (Hylobates agilis) can weigh up to 8 kg (wikipedia.org), and the white-handed gibbon (Hylobates lar) weighs 5-7 kg (sakhalinzoo.ru).

Quote pp. 158-159.

Ligaments of the Hip-Joint. – Professor Bischoff (1) observed that the ligamentum teres of the hip-joint was well developed in the Gorilla. This observation has several times been verified in the Chimpanzee: Owen (2) and Langer (3) found it absent in the Orang, although traces were present. In the Gibbon it is invariably present, and after the limb was severed from the trunk by all but the ligamentum teres, I found it sustained a weight of 25 lbs [11.3 kg]. without rupturing. Morphologically, it may be part of the general capsule of the joint, which has been cut off by the confluence of the lateral wings of the caput femoris, just as a part of the ligamentum posticum of the knee-joint would be isolated were the condylar extremities of the femur to coalesce. The whole of the femoral neck is included in the capsule; and as Owen (2) observed in the Orang, the anterior and inferior aspects of the neck are covered by synovial membrane. Cowper's baud, evidently of the same nature as the ligamentum teres, from which it has been separated by the confluence of the articular surface of the caput femoris, runs along the undersurface of the neck, adherent to the periosteum. A synovial mesentery binds the lower part of Cowper's band to the capsule of the joint.

IMPROVING POSTOPERATIVE COMFORT...

Improving Postoperative Comfort and Increasing the Reliability of Hip Prostheses by Supplementing with Artificial Ligaments: Proof of Concept and Prototype Demonstration S.V. Arkhipov, Independent Researcher, Joensuu, Finland CONTENT [i] Abstract [ii] Introduction [iii] Materials and Methods [iv] Results and Discussion [v] Static Tests [vi] Dynamic Tests [vii] Prototype Fabrication and Testing [viii] Conclusion [ix] References [x] Application [i] Abstract The principle of operation of an experimental total hip endoprosthesis augmented with ligament analogs has been demonstrated in single-leg vertical stances and at the mid-stance phase of the single-support period of gait. The experiments were conducted on a specially designed mechatronic testing rig. The concept of the important role of the ligamentous apparatus is further illustrated by a set of demonstrative mechanical models. The...

Catalog. Classifications of LCF Pathology

The classifications are intended to systematize of ligamentum capitis femoris pathology and assist in the development of general approaches to its description, registration, analysis and treatment. Keywords ligamentum capitis femoris, ligamentum teres, ligament of head of femur, hip joint, histology, pathological anatomy, pathology, trauma INTRODUCTION In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. The development of arthroscopic surgery has made it possible to identify various, previously undescribed types of LCF pathology, which prompted the development of various modern classifications based on intraoperative observations. Analysis of literature data and our own morphological observations allowed us to propose a General Classification of the Ligamentum Teres Pathology, which has the form of a collection of classifiers, as well as a Classification of Functions of the Ligamentum Teres. The ...

The First Scientific Mention

European science has known the LCF for about 2500 years. It is the most important functional connection of the hip joint. The first person to describe the LCF was Hippocrates (c. 460-370 BCE). A written mention of the LCF is found in §1 of his treatise "On the Instrument of redactions". In our opinion, a book created in the library of the Asclepeion of the island of Kos. Hippocrates did not dissection of the human body, did not operate on the hip joint, did not have a CT scan and MRI. How he could discover the LCF? In our view, it is possible that Hippocrates treated a patient with an open hip dislocation.

Human Children. Retelling of Chapter 12

Short retelling of chapter 12 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian] Chapter 12. THE JOURNEYS OF ABRAHAM The narrative begins with Shem, Noah’s eldest son, who, two years post-flood, fathers Arpachshad. Genesis doesn’t clarify where their tribe resides—whether in the "Ararat mountains," the "land of Nod," or already in "Shinar." Generations pass through Shelah and Eber, leading to Peleg, during whose lifetime "the earth was divided." The original audience likely understood this phrase, though its meaning eludes us today. Subsequent patriarchs include Reu, Serug, Nahor, and Terah, who at seventy fathers Abram (Abraham), Nahor, and Haran. Haran sires Lot and dies in "Ur-Kasdim" during Terah’s lifetime, marking the tribe’s presence there. For unspecified reasons, Terah, with grandson Lot, son Abraham, and daugh...

LCF in English Bibles

The primary source for translating the Bible into English is the Hebrew literary monument Torah. In its first part, the Book of Bereshit (32:33 ) , there is a mention of ligamentum capitis femoris (LCF), which in Hebrew is called « גיד » (gheed, gid) (1923, 2004PreussJ; 2019ArkhipovSV_SkvortsovDV; 2020ArkhipovSV_ProlyginaIV). Probably one of the earliest written translations of the Bible into Old English was made by Ælfric of Eynsham, who worked approximately between 955–1010 CE (1050Aelfric’s). In Aelfric's Anglo-Saxon Paraphrase, the Hebrew concept of « גיד » [gheed], that is, LCF, is mentioned twice in the 25th and 32nd verses of the XXXII Chapter of the Book of Genesis and is called «sine» ( Figure 1, 2 ). In Middle English, translators Nicholas of Hereford and John Wycliffe named LCF as «synwe», and in John Purvey's Bible edition - «senewe» (1850ForshallJ_MaddenF). In Bibles in Early Modern English, LCF is designated as «senow» and «senowe» (1530TyndaleW; 1535CoverdaleM; 1...
